These should be the final fixes for the soc tree for 6.8, as usual
they mostly deal wtih dts files:
- Qualcomm fixes for pcie4 on sc8280xp, a revert of msm8996 mpm support,
sm6115 interconnect and sm8650 gpio.
- Two fixes for Tegra234 ethernet
- A Makefile fix to actually build the allwinner based orange pi zero 2w
device tree
- Fixes for clocks and reset on imx8mp and a DSI display regression
on imx7.
The non-DT fixes are:
- Firmware fixes addressing a kernel panic in op-tee and a minor regression
in microchip/riscv.
- A defconfig change to bring back backlight support after a Kconfig change

This reduces the link speed of the PCIe bus with WiFi-card connected on the
Lenovo ThinkPad X13s and the Qualcomm Compute Reference Device, avoid
link errors and initialization issues reported by users.
It also reverts the enablement of MPM on MSM8996, which is reported to
prevent boards on this platform from booting for some users.

Commit 09896da073 ("arm64: dts: qcom: msm8996: Hook up MPM") has
hooked up the MPM irq chip on the MSM8996 platform. However this causes
my Dragonboard 820c crash during bootup (usually when probing IOMMUs).
Revert the offending commit for now. Quick debug shows that making
tlmm's wakeup-parent point to the MPM is enough to trigger the crash.

SETUP_RNG_SEED in setup_data is supplied by kexec and should
not be reserved in the e820 map.
Doing so reserves 16 bytes of RAM when booting with kexec.
(16 bytes because data->len is zeroed by parse_setup_data so only
sizeof(setup_data) is reserved.)
When kexec is used repeatedly, each boot adds two entries in the
kexec-provided e820 map as the 16-byte range splits a larger
range of usable memory. Eventually all of the 128 available entries
get used up. The next split will result in losing usable memory
as the new entries cannot be added to the e820 map.

The current method for signaling the compatibility of a Hyper-V host
with MSIs featuring 15-bit APIC IDs relies on a synthetic cpuid leaf.
However, for higher VTLs, this leaf is not reported, due to the absence
of an IO-APIC.
As an alternative, assume that when running at a high VTL, the host
supports 15-bit APIC IDs. This assumption is safe, as Hyper-V does not
employ any architectural MSIs at higher VTLs
This unblocks startup of VTL2 environments with more than 256 CPUs.

In a CoCo VM, when transitioning memory from encrypted to decrypted, or
vice versa, the caller of set_memory_encrypted() or set_memory_decrypted()
is responsible for ensuring the memory isn't in use and isn't referenced
while the transition is in progress. The transition has multiple steps,
and the memory is in an inconsistent state until all steps are complete.
A reference while the state is inconsistent could result in an exception
that can't be cleanly fixed up.
However, the kernel load_unaligned_zeropad() mechanism could cause a stray
reference that can't be prevented by the caller of set_memory_encrypted()
or set_memory_decrypted(), so there's specific code to handle this case.
But a CoCo VM running on Hyper-V may be configured to run with a paravisor,
with the #VC or #VE exception routed to the paravisor. There's no
architectural way to forward the exceptions back to the guest kernel, and
in such a case, the load_unaligned_zeropad() specific code doesn't work.
To avoid this problem, mark pages as "not present" while a transition
is in progress. If load_unaligned_zeropad() causes a stray reference, a
normal page fault is generated instead of #VC or #VE, and the
page-fault-based fixup handlers for load_unaligned_zeropad() resolve the
reference. When the encrypted/decrypted transition is complete, mark the
pages as "present" again.

set_memory_p() is currently static. It has parameters that don't
match set_memory_p() under arch/powerpc and that aren't congruent
with the other set_memory_* functions. There's no good reason for
the difference.
Fix this by making the parameters consistent, and update the one
existing call site. Make the function non-static and add it to
include/asm/set_memory.h so that it is completely parallel to
set_memory_np() and is usable in other modules.

In preparation for temporarily marking pages not present during a
transition between encrypted and decrypted, use slow_virt_to_phys()
in the hypervisor callback. As long as the PFN is correct,
slow_virt_to_phys() works even if the leaf PTE is not present.
The existing functions that depend on vmalloc_to_page() all
require that the leaf PTE be marked present, so they don't work.
Update the comments for slow_virt_to_phys() to note this broader usage
and the requirement to work even if the PTE is not marked present.

riscv: Fix pte_leaf_size() for NAPOT
Revert "riscv: mm: support Svnapot in huge vmap"
Link: https://lore.kernel.org/r/20240227205016.121901-1-alexghiti@rivosinc.com

This reverts commit ce173474cf.
We cannot correctly deal with NAPOT mappings in vmalloc/vmap because if
some part of a NAPOT mapping is unmapped, the remaining mapping is not
updated accordingly. For example:
ptr = vmalloc_huge(64 * 1024, GFP_KERNEL);
vunmap_range((unsigned long)(ptr + PAGE_SIZE),
(unsigned long)(ptr + 64 * 1024));
leads to the following kernel page table dump:
0xffff8f8000ef0000-0xffff8f8000ef1000 0x00000001033c0000 4K PTE N .. .. D A G . . W R V
Meaning the first entry which was not unmapped still has the N bit set,
which, if accessed first and cached in the TLB, could allow access to the
unmapped range.
That's because the logic to break the NAPOT mapping does not exist and
likely won't. Indeed, to break a NAPOT mapping, we first have to clear
the whole mapping, flush the TLB and then set the new mapping ("break-
before-make" equivalent). That works fine in userspace since we can handle
any pagefault occurring on the remaining mapping but we can't handle a kernel
pagefault on such mapping.
So fix this by reverting the commit that introduced the vmap/vmalloc
support.

The [ms]envcfg CSR was added in version 1.12 of the RISC-V privileged
ISA (aka S[ms]1p12). However, bits in this CSR are defined by several
other extensions which may be implemented separately from any particular
version of the privileged ISA (for example, some unrelated errata may
prevent an implementation from claiming conformance with Ss1p12). As a
result, Linux cannot simply use the privileged ISA version to determine
if the CSR is present. It must also check if any of these other
extensions are implemented. It also cannot probe the existence of the
CSR at runtime, because Linux does not require Sstrict, so (in the
absence of additional information) it cannot know if a CSR at that
address is [ms]envcfg or part of some non-conforming vendor extension.
Since there are several standard extensions that imply the existence of
the [ms]envcfg CSR, it becomes unwieldy to check for all of them
wherever the CSR is accessed. Instead, define a custom Xlinuxenvcfg ISA
extension bit that is implied by the other extensions and denotes that
the CSR exists as defined in the privileged ISA, containing at least one
of the fields common between menvcfg and senvcfg.
This extension does not need to be parsed from the devicetree or ISA
string because it can only be implemented as a subset of some other
standard extension.

Use bpf_jit_binary_pack_alloc for memory management of JIT binaries in
ARM64 BPF JIT. The bpf_jit_binary_pack_alloc creates a pair of RW and RX
buffers. The JIT writes the program into the RW buffer. When the JIT is
done, the program is copied to the final RX buffer
with bpf_jit_binary_pack_finalize.
Implement bpf_arch_text_copy() and bpf_arch_text_invalidate() for ARM64
JIT as these functions are required by bpf_jit_binary_pack allocator.

crypto: arm64/neonbs - fix out-of-bounds access on short input
crypto: lskcipher - Copy IV in lskcipher glue code always
The prologue generation code has been modified to make the callback
program use the stack of the program marked as exception boundary where
callee-saved registers are already pushed.
As the bpf_throw function never returns, if it clobbers any callee-saved
registers, they would remain clobbered. So, the prologue of the
exception-boundary program is modified to push R23 and R24 as well,
which the callback will then recover in its epilogue.
The Procedure Call Standard for the Arm 64-bit Architecture[1] states
that registers r19 to r28 should be saved by the callee. BPF programs on
ARM64 already save all callee-saved registers except r23 and r24. This
patch adds an instruction in prologue of the program to save these
two registers and another instruction in the epilogue to recover them.
These extra instructions are only added if bpf_throw() is used. Otherwise
the emitted prologue/epilogue remains unchanged.

MKTME repurposes the high bit of physical address to key id for encryption
key and, even though MAXPHYADDR in CPUID[0x80000008] remains the same,
the valid bits in the MTRR mask register are based on the reduced number
of physical address bits.
detect_tme() in arch/x86/kernel/cpu/intel.c detects TME and subtracts
it from the total usable physical bits, but it is called too late.
Move the call to early_init_intel() so that it is called in setup_arch(),
before MTRRs are setup.
This fixes boot on TDX-enabled systems, which until now only worked with
"disable_mtrr_cleanup". Without the patch, the values written to the
MTRRs mask registers were 52-bit wide (e.g. 0x000fffff_80000800) and
the writes failed; with the patch, the values are 46-bit wide, which
matches the reduced MAXPHYADDR that is shown in /proc/cpuinfo.

In commit fbf6449f84 ("x86/sev-es: Set x86_virt_bits to the correct
value straight away, instead of a two-phase approach"), the initialization
of c->x86_phys_bits was moved after this_cpu->c_early_init(c). This is
incorrect because early_init_amd() expected to be able to reduce the
value according to the contents of CPUID leaf 0x8000001f.
Fortunately, the bug was negated by init_amd()'s call to early_init_amd(),
which does reduce x86_phys_bits in the end. However, this is very
late in the boot process and, most notably, the wrong value is used for
x86_phys_bits when setting up MTRRs.
To fix this, call get_cpu_address_sizes() as soon as X86_FEATURE_CPUID is
set/cleared, and c->extended_cpuid_level is retrieved.

Pull cxl fixes from Dan Williams:
"A collection of significant fixes for the CXL subsystem.
The largest change in this set, that bordered on "new development", is
the fix for the fact that the location of the new qos_class attribute
did not match the Documentation. The fix ends up deleting more code
than it added, and it has a new unit test to backstop basic errors in
this interface going forward. So the "red-diff" and unit test saved
the "rip it out and try again" response.
In contrast, the new notification path for firmware reported CXL
errors (CXL CPER notifications) has a locking context bug that can not
be fixed with a red-diff. Given where the release cycle stands, it is
not comfortable to squeeze in that fix in these waning days. So, that
receives the "back it out and try again later" treatment.
There is a regression fix in the code that establishes memory NUMA
nodes for platform CXL regions. That has an ack from x86 folks. There
are a couple more fixups for Linux to understand (reassemble) CXL
regions instantiated by platform firmware. The policy around platforms
that do not match host-physical-address with system-physical-address
(i.e. systems that have an address translation mechanism between the
address range reported in the ACPI CEDT.CFMWS and endpoint decoders)
has been softened to abort driver load rather than teardown the memory
range (can cause system hangs). Lastly, there is a robustness /
regression fix for cases where the driver would previously continue in
the face of error, and a fixup for PCI error notification handling.
Summary:
- Fix NUMA initialization from ACPI CEDT.CFMWS
- Fix region assembly failures due to async init order
- Fix / simplify export of qos_class information
- Fix cxl_acpi initialization vs single-window-init failures
- Fix handling of repeated 'pci_channel_io_frozen' notifications

The bit-sliced implementation of AES-CTR operates on blocks of 128
bytes, and will fall back to the plain NEON version for tail blocks or
inputs that are shorter than 128 bytes to begin with.
It will call straight into the plain NEON asm helper, which performs all
memory accesses in granules of 16 bytes (the size of a NEON register).
For this reason, the associated plain NEON glue code will copy inputs
shorter than 16 bytes into a temporary buffer, given that this is a rare
occurrence and it is not worth the effort to work around this in the asm
code.
The fallback from the bit-sliced NEON version fails to take this into
account, potentially resulting in out-of-bounds accesses. So clone the
same workaround, and use a temp buffer for short in/outputs.

Merge tag 'arm-fixes-6.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull arm and RISC-V SoC fixes from Arnd Bergmann:
"The Rockchip and IMX8 platforms get a number of fixes for dts files in
order to address some misconfigurations, including a regression for
USB-C support on some boards.
The other dts fixes are part of a series by Rob Herring to clean up
another class of dtc compiler warnings across all platforms, with a
few others helping out as well. With this, we can enable the warning
for the coming merge window without introducing regressions.
Conor Dooley has collected fixes for RISC-V platforms, both for the
dts files and for platofrm specific drivers.
The ep93xx platform gets a regression for for its gpio descriptors"

Pull arm64 fixes from Will Deacon:
"A simple fix to a definition in the CXL PMU driver, a couple of
patches to restore SME control registers on the resume path (since
Arm's fast model now clears them) and a revert for our jump label asm
constraints after Geert noticed they broke the build with GCC 5.5.
There was then the ensuing discussion about raising the minimum GCC
(and corresponding binutils) versions at [1], but for now we'll keep
things working as they were until that goes ahead.

syncobj, ttm and buddy fixes.
On the driver side, ivpu, meson, i915 have a small fix each. Then
amdgpu and xe have a bunch. Nouveau has some minor uapi additions to
give userspace some useful info along with a Kconfig change to allow
the new GSP firmware paths to be used by default on the GPUs it
supports.
